The correct answer is:
B
Step 1: Understand the concept of inductance in electrical circuits. Inductance is the property of a conductor by which a change in current flow generates an electromotive force (emf) across the conductor.
Step 2: Identify the types of inductance. There are two main types of inductance:
  • Self Inductance: This occurs when a change in current in a coil induces an emf in the same coil.
  • Mutual Inductance: This occurs when a change in current in one coil induces an emf in a different but nearby coil.
Step 3: Recognize the unit of inductance. The unit of inductance in the International System of Units (SI) is the Henry (H). Both self inductance and mutual inductance are measured in Henry.
Conclusion: Hence, the correct answer is that Henry is the unit of both self inductance and mutual inductance.
Therefore, the answer is option B.
